I don't see calling out that ethnic cleansing is bad to be "bullying" and as noted that's a disturbing view to hold at any age (also a quite unChristian one at that.)
I just fail to see how supposedly how you are carrying yourself here is making the forum a nicer place. It does nothing to change mod policy, it does nothing to change a significant number of opinions, and it does nothing to constructively change anything here.
You don't like him. That's ok. Do you need to fight him like this? No. Everyone knows what you think about him. Why not stop?
The forum doesn't have to be a "nicer" place, and the obsession with that is a major part of the tone that's driven a lot of good posters to reduce their involvement here or leave completely. Young people with reprehensible views need it to be made clear (through derision or through any other means) that those views are unacceptable.
You need to stop trying to be friends with everyone. Bending over backwards to make nice with people who would like to see you deported or dead doesn't look good.
